Wehrli Custom Fabrication WCF100196-BS Secondary Coolant Tank Kit 6.7L Powerstroke

The Wehrli Custom Fabrication WCF100196-BS Secondary Coolant Tank Kit is a fabricated aluminum replacement coolant reservoir designed for the 2017–2024 Ford 6.7L Power Stroke diesel engine. This kit replaces the factory plastic secondary coolant reservoir located on the passenger side front of the engine bay, delivering a durable, high-quality upgrade that enhances the appearance and reliability of your Super Duty's cooling system.

The stock plastic coolant reservoirs are known to yellow and cloud over time, and their integrated low-coolant sensors are prone to premature failure — requiring full reservoir replacement each time. The WCFab tank solves both issues with a robust fabricated aluminum construction and a serviceable float-type low coolant level sensor that can be replaced independently, saving time and money over the life of the vehicle.

Key Features:

• Fabricated aluminum construction — durable and corrosion-resistant
• Mounts in the OEM location using factory mounting points — no modifications required
• Retains all factory hose connections for a direct, plug-and-play installation
• Includes black anodized CNC machined billet aluminum cap
• Billet aluminum coolant level sight glass for easy fluid monitoring
• Serviceable low coolant level sensor — replaceable without replacing the entire tank
• Includes overflow hose and all necessary mounting hardware
• Custom powder coat finish for a clean, show-quality appearance under the hood
• Made in the USA by Wehrli Custom Fabrication

Installation is straightforward using basic hand tools, following the OEM mounting points and supplied hardware. The WCF100196-BS is the ideal upgrade for Ford Super Duty owners looking to eliminate a known factory weak point while cleaning up their engine bay with a premium custom finish.
